Answer:
x = -1,5.4
Step-by-step explanation:
We have to solve equation f(x) = g(x) from graph.
In graph f(x) and g(x) will be equal at the point where they meet each other.
Other way to understand this is
since y will be value of f(x) and g(x) .
so we need same value of y for both f(x) and g(x)
and same value for y will be at point where both function meets each other.
now looking at graph ,
we can see that graph of function f(x) and g(x) intersect at two points
(-1,-10) and other is at (5.4,12)
Thus, value of x from pair of solutions (-1,-10) and (5.4,12) is x = -1, 5.4.
Answer:
The first is traveling at 51 mph.
The second is traveling at 61 mph.
Step-by-step explanation:
The first is traveling at 51 mph.
The second is traveling at 61 mph.
Hello there! So, y = mx + b is in slope-intercept form, where m represents the slope, b represents the y-intercept, and y and x remain unfilled. First off, let's solve for the slope. The formula for slope is y2 - y1 / x2 - x1, where you subtract the first x and y coordinates from the second x and y coordinates. So it would be formed like this:
9 - 4 / 6 - (-4)
Let's subtract. 9 - 4 is 5. 6 - (-4) is 10. 5/10 is 1/2 in simplest form. The slope for this equation is 1/2. Now, let's find the y-intercept. We will find that by plugging one of the points into the equation and solving for b. The x and y coordinates will be filled in by that coordinate. Let's use (-4, 4) for this problem. We will also plug in the slope. In this case, the problem will look like this:
4 = (1/2)(-4) + b
Now, let's multiply 1/2 and -4 to get -2. Now, to get b by itself, subtract 2 to both sides to isolate the b. -2 + 2 cancels out. 4 + 2 is 6. b = 6. There. The equation of the line in slope-intercept form is y = 1/2x + 6.
Four ratios:
light to dark: 4:12
dark to light: 12:4
black to white: 2:4
white to gray: 4:10
gray to white: 10:4
any of those work.
They would have used a total of 30 horses. Each person would've each ridden 15 so 15+15= 30 and 165 divided by 11 is 15. Hope this is off help!
